    The Internet of Things (IoT) network is typified by deployments such as a Wireless Sensor Network (WSN). These WSN's are commonly deployed within a target area for a specific task such as farm monitoring and asset movement control. A group of sensors are typically led by a Personal Area Network Coordinator (PANC). In some situations like in large scale greenhouse monitoring, mobile PANC are required to eliminate energy-hole issues and hence improve the performance of the WSN. The energy-hole issue is a problem caused by the depleted cluster head nodes. In this paper we analyse the performance of a WSN with a mobile PANC. Using inputs from previous empirical studies we designed a scenario of a mobile PAN coordinator using a simulation package. The performance was evaluated. The mobile PANC speed and contact time is monitored and the average network throughput and delay are measured. Based on an analysis of these results a comprehensive set of guidelines are provided for operators of IoT networks. These guidelines optimise the network performance and ultimately lead to cost savings for network providers.

    Purpose: This study aims to review the last 50 years of academic research on collective leadership (CL) and how far it has progressed by using the Scopus database and the science mapping technique of bibliometric analysis. Design/methodology/approach: This study has analysed 417 publications from the Scopus database on collective leadership from 1967 to 2023. Data were analysed using MS Excel and VOSviewer. Findings: There has been research from different parts of the world on the various aspects of collective leadership. In recent years, collective leadership research has gained momentum. However, collective leadership is still at a nascent level when it comes to the applicability of the concepts. So far, the research on collective leadership has relied on themes such as shared leadership and distributed leadership, how collective leadership differs from other similar-looking leadership styles such as transformational leadership, and how this influences followers’ outcomes such as team effectiveness, achievements, relations, commitment, etc. Most of the research so far has been done in the United States of America, the UK and the Australian context. There exists a huge gap for studying collective leadership in African, Middle Eastern and Asian contexts. Research limitations/implications: Collective leadership research trends may be addressed to enable academics and practitioners to better understand current and future trends and research directions. Future studies in this field might use the findings as a starting point to highlight the nature of the topic. Originality/value: Bibliometric techniques provide a far more comprehensive and reliable picture of the field. This article has the potential to serve as a one-stop resource for researchers and practitioners seeking information that can aid in transdisciplinary endeavours by leading them to recognized, peer-reviewed papers, journals and networks.

    The rapid expansion of Social Media (SM) has revolutionised consumer interactions with digital content, creating both opportunities and challenges for businesses aiming to influence purchase intention. This study investigates how perceived value, informativeness, and personalisation shape purchase intention on SM platforms among university students at Universiti Malaysia Perlis (UniMAP), Malaysia. Addressing the need to understand the drivers of effective digital marketing, the research employs a cross-sectional design with data collected via a random survey of 375 students. Multiple regression analyses reveal that while perceived value and informativeness positively influence purchase intention, personalisation unexpectedly demonstrates a negative relationship. These findings underscore the nuanced role of personalised advertising and the potential privacy concerns associated with it. The results highlight informativeness as the most significant predictor of purchase intention, emphasising the importance of delivering relevant and valuable content. In contrast, personalisation’s negative impact suggests a need for cautious implementation to avoid alienating consumers. This study enriches existing literature by bridging theoretical insights with practical applications, offering actionable strategies for optimising consumer engagement in digital marketing. Practical implications emphasise balancing value delivery and addressing consumer apprehensions in personalised marketing to enhance consumer trust and drive purchase behaviour effectively. This research offers a foundation for future exploration of consumer behaviour in SM contexts.

    Nowadays, numerous activities have been conducted by all the people and government to support green concept. However there is still exist issue regarding the environment occur in Malaysia such as the cost of waste management from 2016 to 2017 are keep increasing from RM200 million to RM250 million. There were three objectives in this research that are (1) To examine the social influence effecting green purchasing behaviour towards ecological product; (2) To examine the environmental concern in influencing green purchasing behaviour towards ecological product; (3) To examine the environment attitude in influencing green purchasing behaviour towards ecological product. To complete this study, researcher used Theory of Planned Behaviour (TPB) to underpinning the study. Primary data were collected through questionnaire by using 5-point likert scale in order to investigate our research objective. 268 sets of questionnaire were collected from University Malaysia Perlis (UniMAP) students. The SPSS was used to analyse the descriptive analysis, reliability test, multiple regression and Pearson correlation analysis. The result show that the there are two significant factor that influence green purchasing behaviour towards ecological product among students that is social influence and environmental attitude but not significant factor is environmental concern. Thus, this study also suggested future research could be done, whereby researcher could get larger sample size and by doing sample using actual purchaser of ecological product to improve the understanding of green purchasing behaviour.

    The purpose of this paper is to evaluate the quality of healthcare services by investigating the factors affecting patient satisfaction and predictors in private hospitals in Georgetown, Penang, Malaysia based on three service quality dimensions of the SERVQUAL which Responsiveness, Reliability, and Tangibility. A modified SERVQUAL questionnaire was used using random sampling to gather the research data and the respondents are consisted of 204 public and outside patients who are prior to the onset of the investigation. Pilot test is conducted for 54 respondents and all the variables obtain Cronbach's Alpha more than 0.7 which is acceptable. Statistical Package for the Social Science (SPSS) is used to evaluate data of this research. The results of the study revealed that the perceived healthcare services in private hospitals do not significantly vary. The dimension of responsiveness was rated the highest while tangibility was perceived as the least important of the three SERVQUAL dimensions applied in this study. Therefore, this research suggests to use more dimensions of service quality theories and bigger samplings to obtain better results and may be used to contribute in enhancing the quality of healthcare services of private hospitals in Penang, Malaysia and in other similar environments.

    WSN technology has now become ubiquitous due to its flexibility, efficiency and affordability. For example the nodes in a WSN can be easily deployed in any targeted area and last for many years. The nodes can supply reliable data from within the environment with minimal disturbance to the target area.However challenges remain in providing real-time communication in some communication hostile conditions. It may not always be possible to leave the sensors in situ but instead data collection is through the use of mobile a WSN. For example as a vehicle fitted with sensing devices passes through an area of interest data is collected and relayed at certain gateway nodes back to a backhaul network for processing.In this paper our aim is to analyse the interference caused by a mobile jammer node to the stationary transmitter and receiver nodes in a network by using the OPNET Modeler software. This is early stage work aimed at developing a mobile WSN node in our future research.

    E-commerce is in rapid growth nowadays. An SME has to adopt e-commerce in order to continue surviving in an intensely competitive environment. However, it was showed that there is a slow succession from the use of e-commerce among tourism-based SMEs in Melaka, Malaysia. As a result, this research is carried out to identify the factors of e-commerce adoption. Technology, Organization, and Environment (TOE) Framework by Tornatzky, Fleischer, and Chakrabarti and Diffusion of Innovation (DOI) Theory by Rogers were used in this research to explain the independent variables in affecting e-commerce adoption. Along with, this research also analyzed the demographic information, descriptive results, strength of each independent variable towards the dependent variables. Generally, this research is a quantitative study. 15 respondents were selected in the pilot test. All the variables are excellent reliability due to the Cronbach’s alpha of more than 0.80. Convenience sampling technique was being chosen to collect our research data. The questionnaire was distributed to 118 respondents of tourism-based Small and Medium Enterprises (TSMEs) in Melaka, Malaysia. Statistical Package for the Social Sciences (SPSS) was used to analyze the data of this research. From the result of Regression Analysis, it was found out that technological context, organizational context, environmental context, and individual context have a positive relationship with e-commerce adoption. Therefore, the organizations are able to increase their e-commerce performance by verifying the factors in their e-commerce system. This research suggests the future researchers to replicate the study in other industries or the other states in Malaysia which involved a bigger size of the population to make the result more generalize and increase its accuracy. Future researchers also may distribute the questionnaire by visit personally to the SMEs rather than the online distributive survey in order to have a faster response from the respondents.

    The purpose of this research was to investigate factors that influence the effectiveness of the e-learning system in a higher learning institution. The participants were students randomly selected from diploma and degree programs. The main instrument was a questionnaire that was distributed to the students. The researchers collected 205 completed questionnaires out of a total of 300. Four factors were chosen as independent variables namely: reaction and satisfaction, learning outcome and achievement, familiarity with online learning technology, and participation and interaction. It was found that the effectiveness of the e-learning system was significantly affected by reaction and satisfaction, learning outcome and achievement, and familiarity with online learning technology. The participation and interaction factor had no apparent effect on the effectiveness of the e-learning system. Therefore, it is recommended that higher learning institutions interested in introducing e-learning should focus on students’ reaction and satisfaction towards the system. E-learning should focus on learning outcomes and achievement. It is also recommended that institutions first look into the issue of familiarity with online learning technology among students before introducing the e-learning system so as to determine whether students are comfortable with the online learning tools.
